Title: Manufacture of trifluoromethylphenylsulphones
IPC: C07C317/14
Filed: 1936-08-12
Abstract: Trifluoromethylphenylsulphones of the formula R.SO2.CF3, in which R represents a substituted or unsubstituted benzene radicle, are prepared by treating the corresponding compounds R.S.CCl3 with anhydrous hydrogen fluoride or antimony trifluoride at a raised temperature and oxidizing the products.  The sulphones are useful in the manufacture of dyestuffs, pharmaceutical compounds, fungicides and insecticides.  According to the examples: (1) trichloromethylphenylsulphide is heated in an iron autoclave with technically anhydrous hydrogen fluoride and the resulting trifluoromethylphenylsulphide then heated with chromic anhydride and sulphuric acid to form the sulphone; (2) p-chloro-trichloromethyl-sulphide is heated with antimony trifluoride in an iron vessel provided with a rectifying column and the product oxidized with chromic anhydride and glacial acetic acid; in the same way, the o-chloro-, m-chloro, 3 : 4-dichloro-, 2 : 5-dichloro-and 2 : 4 - dichloro - trichloromethylphenylsulphides may be treated, as well as the mono- and poly-bromo derivatives; (3) o-, m- and p-trichloromethyltolylsulphides are converted as in (1) into the trifluoromethyltolylsulphones and phenyl - 1 : 3 - bis - trichloromethylsulphide into phenyl-1 : 3-bis-trifluoromethylsulphone; their halogen and methyl derivatives may also be produced; (4) 4-nitro-1-trichloromethylphenylsulphide and its 2-chloro derivative are transformed into the corresponding trifluoromethylphenylsulphones; from 4 - nitro - 3 - trichloromethyl - 1 - trichloromethylphenylsulphide is obtained 4 - nitro - 3 - trifluoromethyl - 1 - trifluoromethylphenylsulphone; (5) 3 - nitro - 1 - trichloromethylphenylsulphide and its 4-chloro-derivative are converted into the corresponding trifluoromethylphenylsulphones; (6) 3 - trifluoromethyl - 1 - trifluoromethylphenylsulphone is prepared from 3-trifluoromethyl-1-trichloromethylphenylsulphide.

Title: Method and a device for introducing inner tubes into tyres
IPC: B23P19/08
Filed: 1973-05-10
Abstract: 1432996 Introducing toroidal members into tyres BOUSSOIS SA 10 May 1973 [25 May 1972 22 March 1973] 22459/73 Heading B7C A method, illustrated with the aid of Fig. 1, of introducing a toroidal member containing air into a tyre, comprises: deforming the member such that opposite radially inner faces of the member are brought into close proximity, or into contact, so as to elongate the member; thrusting the elongated member into the tyre in a direction parallel to the direction of the elongation; the member being inserted through an opening in one face of the tyre and at an oblique angle to the mid-circumferential plane of the tyre; preventing the member from escaping from the opening of the other face of the tyre while guiding the member towards the internal periphery of the tyre; and continuing to thrust the member into the tyre until it is finally positioned inside the tyre. The method is applicable to the insertion of conventional, hollow, inner tubes into tyres, but is stated to be particularly suitable to the insertion of a "puncture-proof" inner tube formed of moulded rubber having a large number of compartments which are inflated during manufacture to a predetermined pressure. In a first embodiment, Fig. 2, of device for carrying out the method, the inner tube 1 is deformed in operation of the device, by a jack 9 until opposite radially inner faces of the inner tube are brought into contact and the inner tube is secured in the deformed condition by means of ties (24), Fig. 3 (not shown). The inner tube is then engaged in an oval-section guide tube 14 and the ties removed. A funnel 15 comprising separable elements (15a, 15b, 15c), Fig. 3 (not shown), is then attached to the guide tube 14. The funnel 15 has a flange 17 engaging within a tyre opening. A jack 12 is then actuated to thrust the inner tube through the funnel 15 and into the tyre. A deflector 5 engaged on the tyre guides the inner tube into the inner periphery of the tyre. In a second embodiment, Fig. 6, of the device, the funnel 31 comprises two half-shells 32 pivotally mounted on the guide tube 14. The half-shells 32 have flanges 35 for engagement in a tyre opening. In use of the device of Fig. 6, the undeformed inner tube 1 is placed between wings 26 and pushed into the guide tube 14 by a jack 12. In a third embodiment, Fig. 11, of the device, the inner tube 1 is deformed between a fixed side-plate 37 and a movable side-plate 38.

Title: Process for obtaining pure ª† isomer of benzene hexachloride
IPC: C07C17/38
Filed: 1950-09-13
Abstract: The g -isomer of benzene hexachloride is obtained in a technically pure state by selective crystallization from a solution supersaturated in a -, b - and g -isomers when there has been added thereto "d c" to a concentration of 20-50 per cent by weight, the term "d c" comprising the isomers other than a , b  and g , as well as the by-products of the chlorination of benzene, especially chloro substitution products of benzene hexachloride.  This addition of d c retains the a - and b -isomers in supersaturation and the amount of d c is adjusted in accordance with the amounts of a  and b  present. The starting material is preferably a solution enriched in g -isomer, e.g. as obtained in Specifications 655,686 or 619,677.  In operation, the mother liquor from a previous crystallization cycle is diluted with a little fresh solvent and contacted with fresh benzene hexachloride at crystallization temperature until all the g -isomer is dissolved to a saturated solution thereof.  A quantity of solvent equal to that added is now evaporated off, leaving the solution supersaturated in g -isomer which then crystallizes out.  Before a and b  appear, the solution is filtered and recycled as above.  To maintain the d c concentration constant in continuous operation, a portion of the mother liquor is removed each time, evaporated to dryness and the condensed solvent returned to the solution.  Examples are given of the process, using as solvents isopropyl alcohol, benzene, ethylene chlorhydrin and trichlorethylene.

Abstract: 1511031 Automatic control of temperature and concentration FORD MOTOR CO Ltd 23 May 1975 [1 July 1974] 22623/75 Heading G3R [Also in Division G1] A heater winding is connected in series with a switch and a power source. When the voltage developed across the winding reaches a predetermined value, indicative of its temperature the switch is opened and then reclosed after a fixed time set by a circuit including an oscillator connected through an amplifier to the switch. As shown in Fig. 3, a winding 52 used to heat a variable resistance titania or cobalt monoxide ceramic gas sensor (24) in the exhaust gas line of an internal combustion engine (10), Figs. 1 and 2 (not shown), forms one arm of a resistance bridge 58, 60, 64 connected in series with a switching transistor 54 and a D.C. supply line 50. When the winding 52 reaches the desired temperature, its resistance is arranged to reach a corresponding value which causes the output voltage of the bridge to reverse the polarity of the output of an amplifier 68 so that the transistor 54 is turned off and current ceases to flow in the winding 52. The current is re-established after a fixed time delay set by an oscillatory RC circuit 88, 90, 104 connected to the base of transistor 54 through an amplifier 80. The wafer 48 of the gas sensor, Fig. 4, is responsive to oxygen content of the exhaust gases and is connected in a bridge circuit 116, 118, 123 receiving a regulated supply voltage. The bridge output signal is fed through an amplifier 122 with a linearizing feedback network 126 to an integrating and signal limiting circuit, Fig. 5 (not shown), the output from which is used to control the fuel-air ratio of the mixture supplied to the I.C. engine.
